Cementless Lightweight Materials from CO2-Sequestering Waste Mixtures for Sustainable Construction (Prof. Charles Wang Wai NG)
Problem addressed
Construction and household wastes, including plastic waste and food waste, are recycled and reused to produce sustainable construction materials.
Innovation
- Minimize the use of carbon-intensive cement and natural aggregates that are typically required for production of construction materials
- Sequestrate carbon dioxide (CO2) in mixture of wastes to form cementless construction materials
- Enable production of lighter construction materials with different dimensions to improve construction flexibility
Application
- Produce sustainable and durable materials for construction and earthen structures (e.g., partition walls, pavements, etc.)
- Provide a novel solution to facilitate waste reduction and recycling in the society to achieve sustainable development and carbon neutrality
- Integrated with coating science to provide cooling in surroundings and reduce energy consumption for temperature control
